Inspired by the problem in your text of students who were paid to write essays in support of the police, Lepper, Greene and Nisbett had nursery school children color with Magic Markers. Some children expected to be rewarded and some did not. In addition, half the children received a reward and half did not. Afterward, the children were tested for their interest in coloring with Magic Markers. High scores mean greater interest.
